AUTOMATIC GUIDE FOR ENDLESS APRON SI No. 824,059; Specification )fLetters Patent.

Patented June 19, 1906 7 Original application filed January 21, 1905,Serial No. 242,056. Divided and this application filed September 7,1905.Serial To all whom 712'; may concern:

Be it known that I, ALBERT BESS, -a citizen of the United States,residing at Hamilton,

Butler county, Ohio, have invented a new and useful Improvement inAutomatic Guides for Endless Aprons, of which the following is aspecification.

My invention relates to automatic guides for endless aprons of the classadapted to use in mangles, paper-mills, or elsewhere, and thisapplication is adivision of my application filed January 21, 1905,Serial Nof of a mangle embodying .my improvement;

Fig. 3, an elevation with parts in section on the line a: of Fig. 1;Fig. 4, a plan with parts in section on the line 2 z of Fig. 3 of theguideroll and housing connections, and Fig. 5 a vertical section on theline 'y y of Fig. 3.

In the drawings, 6 and 7 represent the end frames of a mangle, 8 thecylindrical drier journaled therein and rotated by means of gear-wheel 9from driving -pinion 11. An endless apron 12 partially encircles thedrier under padded pressure-rolls 13 and over tightening-rolls 14 and 15and idle supporting-rolls 16 and 17, all being constructed and arrangedin the ordinary manner. Idle supporting-roll 17 is journaled andlongitudinally movable in fixed bearings 18 and 19 and bearing 21 onfixed bracket 2 2.

Bevel-gears 23 and 24, each having a clutch member 25 on its face, aremounted to turn idly on extended journal26 of roll 1.7 contiguous to therespective bearings 19 and 21'. They are in continuous mesh withbevelgear 27, which is secured on screw 28 and journaled thereby inbracket 22. Clutch members 29, secured on journal 26 between thebevel-gears thereon, are movable into or out of engagement with therespective said gears by the longitudinal movements of said journal androll 17. screw 28,.may be rotated in opposite directions by therespective gears 23 and 24.

Guide-roll 31, journaled on housing 32, is

by means of bolt 34. A socket in one end of the housing forms aswivel-joint with spherical nut 36 therein, which is adjustably Gear 27,together with r adjusted on the pivot to maintain the apron in itsnormal direction of travel, with the clutch members on the journal ofthe idle supporting. roll 17 midway between the bevel-gears thereon andout of engagement with either of them. Any lateral deviation of theapron from its normal direction of travel will move the idle roll 17longitudinally in the same direction. movement-of said roll besuflicient to cause either of the clutch members on the journal to becarried into engagement with the adj acent bevel-gear thereon,rotary'motion will thereby be imparted to the intermediate bevel-gearand screw in the proper direction to change the angle of the guide-rollon the pivot and reverse the lateral movement of the apron which willcarry the idle roll with the clutch member out of engagement with thebevel-gear. movement of the apron may be automatically confined withinpredetermined limits.

Having fully described my improvement, what I claim as my invention, anddesire to secure by Letters Patent of the United States, 1s

1. The combination of a pivotally-supported housing, a. roll thereon, alongitudinally -movable roll, and means actuated thereby to changetheangle of the housing on the pivot.

2. The combination of a pivotally-supported housing, a'roll journaledthereon, a roll movable longitudinally and j ournaled in fixed bearings,and screwmechanism automatically engaged and actuated intermittentlythereby to change the angle of the housing on the pivot. I

3. The combination of a housing pivotally supported at a fixed point, aroll journaled thereon, a roll journaled and longitudinally movable infixed bearings, and screw-revers- Should the In this manner the lateral60 pivotally supported thereby on fixed bar 33 ing mechanism adapted tobe automatically a pivotally-supported housing, a guide-roll engaged andactuated thereby to move the housing in opposite directions on thepivot. 4. The combination of a housing movable 5 on a pivot and providedwith an adjustable socket in one end portion, a screw, and a sphericalnut adjustably threaded thereon and movable Within'the socket.

5. The combination of an endless apron, a

10 supporting-roll therefor responding longitudinally to the lateralmovements of the apron,

thereon in contact with the apron, a screw arranged to move the housing,and. reversing mechanism therefor arranged to be automatically engagedand disengaged by the longitudinal movements and actuated by therotative movement of said roll,
